The 32-year-old singer announced her second pregnancy with fiance Eric Johnson on Christmas Day, which came as quite a surprise.

An inside source reveals, “It’s Jessica’s dream come true, she prayed she was having a boy. She found out this week after a check-up at the doctor, who asked her if she wanted to know the sex of the baby.

“Jessica immediately said yes and when the doctor told her it was a boy she screamed with joy. She was so happy that Maxwell is getting a little brother because that’s something she always wanted when she was growing up.

“Jessica and Eric are so excited and have started going through names, but they haven’t settled on one just yet. It’s just a pity their favorite boys name went to their daughter first!”

Jessica Simpson recently revealed her second pregnancy has postponed her wedding plans with Johnson.

Simpson told Jay Leno, “Apparently it was a part of God’s plan for my life … We’ve had two different wedding dates, but he keeps knocking me up. We’re doing it very backwards, I know … I’ll just keep my legs crossed, I guess, this time.”
